of the city of New York, Bronx Countyand "State of New York' have invented certain new and useful Improvements in a; -Feed- Control Stopping Mechanism for. Paper- Foldin Machines,.o f which the fol-lowing :is: a full, clear, and exact-description. Y

Among thewprincipal' objects which the present invention" has 'in view are: To provide anactuating mechanism for thedriving as the result of the failure totdeliver sheets to any predetermined stationto which; the

said sheets are moved; to actuate the stop-- ping'mechanism of the driving mechanism unless prevented by the normal foperation of delivering the folded sheetsjfrom the folding mechanism; to provide correlated circuit closing devices operable; at 'dilfere'nt speeds to conformwith the function of the folding machine to which it is applied; and to provide-a signal fornotifying the stop.- page of the folding machine.

Rampage; u Folding machines which maybe. equipped with the stopping mechanism of the character mentioned are provided at the delivery station. of said folding machines with stacking' troughs into which the folded sheets are delivered on edge to be moved forward out oflthe delivery line tomake room for succeeding sheets. 1 Atv such sta'tions the trough is supplied with some form of yielding detent which. isfrocked'by the passing paper to-be-resiliently or [otherwise returned to its upright positionibehind thewfolded paper for preventingthe'return ofthe .f0l d.

The function theli'ne-18; and deener'gizethe timedjfsolenoid 19each-ti'me the blades iare j'rocked out" of contactfwith gthe back points- 10 which op nism: ,of thefolding'; machine; In'other words; whenever the: stacking me hanis is operating normally to deliver afolded sheet, the solenoid 15% is; de-energ'izedto openIthe folding machine has become choked and the folded Shea dbesnotrockfthe blades 7, the f solenoidc15qmaintains closed {the circuit in- 1 corporating'the wires l8'and the solenoid 19'.

Normally, the solenoid '19 is energized in the positioni'shownin Fig." 2 of the drawings vcircuitflincorporatingthezbranch wire 18 and 1 i thetimed solenoid'19; If-for any reason the,

after the timed] solenoid 20 1195 inove'dfthe J connector 21' into contact' With the, back points 22 of the branch circuit incorporating closed. When the said switch is closed, the circuit incorporatingthe wire 23, solenoid 20, wire 26, switch. 25 and the dynamo 13 is completed. Dash pots 27 regulate the speed of operation of the solenoids 19 and 20. The speed ofthe solenoid 20 is arranged so that after thcsw'itch 25 is closed, asheet of paper being delivered to the machine at that time, will pass through the various folding devices to the stacker before the circuit closers for the stopping mechanism are brought into operation. a

By this arrangement if the circuits incorporating the wires 24, 14;, solenoid 15, blades 7, contact points 10 'iand Wire 11, iscompleted, the solenoid 15 becoming energized the connector 16 is lifted to complete the circuit embodying the wire 18, solenoid 19,

wires 24, 12-and 11. The solenoid 19 now being energized starts to lift the connector 29 to engage the backpo'ints 30; The;back points 30 .are incorporated 'iir'a ci rc'u'it embodying the wire 28, solenoid 31', and the Wires ll, 12, 24 and dynamo 13; The solenoid 31 when energized lifts "the connector 32 away froim the back point contacts 33 of the control circuit for the starting mechanism of the folding machine which is operated on a closed circuit comprising the Wires 34-;

. It is evident that ifthe connector 29 engagesrthe back points 30 to complete the circuit embodying the solenoid 31, the stopping mechanism vfor the folding machine will o'perate to stop the said folding mechanism. This happens whenever paper fiassinp; filllI'O'Ltg'l'] the folding machine does not reach the stacker intimeto rock-the blades '7 away from the back points 10 before the -solenoid 19 has time to liftx'the connector 29 to the back points30'. This always happens in "the event of a choke of the paper ti-"ansp'i'ring in .the folding mechanism.

v Under nori'nal conditions the operation of the folding mechanism on the sta cl'rer and the blade 7 therein is so frequent the he circuit en'ibodying, the: srilenoid 19 "is maintained substantially open, the-dash pct 27 preventing the lift of the connector 29 during the period of-e'lcctri-cal impulse imparted to the solenoid 19. It is only \vl'ieu the inipulse is continued to saturationthat tl'ic connector is lifted to make the cont: complete the circuit incorporating the solei'ioi'd 3i,

By this arrangement it wiil be seen the operator can place hi... feed control. inechan'isn-i in condition to" become operative, subject to the relatively sldiv operation of the folding mechanis'nrin delivering the folded paper to the stacker.
